Seed hardening is a pre-sowing treatment that involves subjecting seeds to certain chemicals to enhance their germination, growth and overall performance under field conditions. The researchers used various chemicals for seed hardening and these treatments included i.e., FeSO4@ 5%, KH2 PO4@2%, KCl@2%, KNO3@2%, MnSO4@100 ppm, ZnSO4@100 ppm, Cobalt nitrate @ 1%,CaCl2 @2%,GA3 @ 40%and Control. The study revealed that seeds hardened with MnSO4@100 ppm resulted in the highest values for various parameters viz., plant height, no. of leaves per plant, no. of branches per plant, no. of nodules per plant, days to first flowering, no. of cluster per plant, no. of pods per plant, pod weight per plant, pod length, no. of seeds per pod, no. of seeds per plant, test weight, pod yield per plant, root length, shoot length, seedling length, seedling fresh weight, seedling dry weight, vigour index-I and vigour index-II. The results showed that black gram seed hardening with MnSO4@100 ppm improved higher seed yield and quality parameters when compared to other treatments and control.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"30 SUPPL","pages":"S373-S378"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://doi.org/10.53550/eec.2024.v30i03s.064","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147879378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This favoured the nutrient balance in improving crop growth and yield potential. Therefore, this field study was conducted during 2021 at a farmer’s field in Srivilliputhur block, Tamil Nadu to assess the effect of foliar application of bio-stimulants and nutrients on transplanted finger millet CO15. The experiment was laid out in Randomized Block Design (RBD) with three replications and eight treatments viz., Control, GA3 @ 50 ppm, Panchagava @ 3%, Seaweed extract (Sargassum wightii) @ 5%, Humic acid @ 5%, Boron @ 0.3%, ZnSO4 @ 0.5% and FeSO4 @ 0.5% sprayed twice at 20 DAT and 45 DAT. Ten characters namely plant height, number of tillers/hill, Leaf area index, dry matter production, number of ear heads/hill, number of fingers/ear head, finger length, test weight, seed yield and straw yield were studied. Among the different foliar treatments, NPK along with the foliar application of ZnSO4 @ 0.5% (T6 ) significantly enhance the growth and yield parameters compared to the other treatments. Hence, foliar application of ZnSO4 @ 0.5% (T6 ) could be adopted to get a higher seed yield.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"30 SUPPL","pages":"S259-S264"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://doi.org/10.53550/eec.2024.v30i03s.045","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147880405","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current study, an examination of the mechanical characteristics of bacterial concrete containing nano-silica is conducted. The impact of concrete was examined in this study employing Bacillus subtilis for self-Healing Microbial Type Culture Collection (MTCC) Strain no.121, Among the bacteria concentrations of 104 , 105 , and 106 cells/ ml, a concentration of 105 cells/ml gives more strength, so further investigation is done using 105 cells/ml cell concentration for different percentages of nano-silica is examined. Firstly, Bacterial cell concentration is optimised. Each of the 40 sets of cubes (150 mm x 150 mm x 150 mm), cylinders (150 mm diameter and 300 mm height), and prisms (100 mm x 100 mm x 500 mm) are cast and tested at 28 days and 90 days as part of further research to determine the mechanical properties of bacterial concrete with different percentage of nano silica with and without bacteria. It has been noted that adding nano-silica to concrete increases its strength from 0% to 1.5% before being decreased to 2%. concrete splintering occurs due to a number of causes, including mechanical compression and low tensile strength, shrinkage, freeze-thaw reaction, and others. External loads can cause high tensile strains. For any combined nano-silica percentage when compared to regular concrete, bacterial concrete is stronger.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73518584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study documented about ”106\" regenerating tree species, representing “74” genera and “40” families from the study area from which about “47” percent of tree species showed “good” regeneration status.

Monoon simiarum showed highest IVI index of 15.19, followed by Aglaia spectabilis (10.41). About 9 percent of the species had “fair” regeneration status and 8 percent had “poor” regeneration status, the fair or poor regeneration might be due to insufficient seed dispersal that limits native species colonisation. However, it was observed that a total of 18 percent of tree species were classified as “not regenerating” and again 18 percent of tree species that were present in either sapling or seedling stage but no adult stage were categorized as new regeneration.","PeriodicalId":11458,"journal":{"name":"Ecology, Environment and Conservation","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74802300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We have surveyed in this paper, the most important written works on the various sorts of plastics underway, the negative impacts of these constituents to air, water, soil, organic entities and human wellbeing viz-a-viz the different removal technique. Papers that revealed ecological and general wellbeing impacts of plastic looked in to assortments of plastic utilized in the creation of numerous consumable items including clinical gadgets, food bundling and water bottles containing harmful synthetic substances like phthalates, weighty metals, and Nonyl phenol. Yearly 8 million tons of plastic is delivered into the sea, prompting corruption of marine living space which at last influences amphibian life forms and creates health hazards.

WBD, which is predominantly instigated by Mycogone perniciosa, might pose a severe danger to A. bisporus output over the world. Because of the similarity between A. bisporus and M. perniciosa, it was predicted that the current study would choose reliable antimycotic agents that could favorably treat this fungal disease on mushrooms. The antimycotic susceptibility of host and pathogen was investigated in vitro using six different fungicides. The effects of chlorothalonil, carbendazim, thiophanate-methyl, azoxystrobin, difenoconazole, and kresoximmethyl on M. perniciosa, the mycoparasite that origins white button mushroom wet bubble disease, were evaluated in vitro and in vivo. Chlorothalonil and carbendazim were the potent antimycotic agents for reducing M. perniciosa mycelial growth in vitro, with inhibitions of 96.93 percent and 94.15 percent, respectively. Chlorothalonil inhibited the pathogen’s mycelial growth at 25-500 ppm, whereas carbendazim did so at 5 to 100 ppm, with least (16.67 percent) inhibition of A. bisporus mycelium. Difenoconazole, kresoximmethyl and azoxystrobin among other fungicides, were shown to be very repressive to the pathogen (91.81 percent, 83.26 percent and 71.05 percent) with the largest percentage of inhibition (87.77 percent, 84.44 percent and 75.55 percent) of A. bisporus mycelium.
